Abstract

A metal cutting drill includes a steel drill body, and a carbide insert (60) brazed therein. The drill body includes a front face (52) having a recess (54) formed therein, the recess radially overlapping a longitudinal axis of the drill body. The insert (60) is brazed in the recess (54) and includes a plurality of spaced-apart cutting edges (62,64,66,68) disposed on opposite sides of the axis. The cutting edges radially overlap during a drilling operation. One of the cutting edges (68) projects radially outwardly beyond a side face of the head, and another of the cutting edges terminates radially inwardly of the side face. <IMAGE>
